i read this article and it claims 5.5% to 6.5% reduction in drag. i searched and didn't see any info here. is this been tried here?

i would like to give it a shot if it sounds like a realistic figure.
i also like the boat tail figure improvement of "
22.6%. At aft rear fairing length being 25% of its full length vehicle model drag factor is reduced by 16.1%."
i am new to all this so if i am missing something, let me know.
